LOUISVILLE, Ky. — Across Louisville, many are getting their plans in place for the Fourth of July. This year, those plans include extra precautions to stay cool. Josh Chang moved to Louisville two weeks ago, just in time for above temperatures to hit the area, and right in time for the holiday weekend. Chang says keeping his young children safe in the heat is a priority throughout the holiday weekend. "My kids are very small, so they get tired easy and are very affected by hot weather," Chang says.
